COMBINATION VALVE GRINDER AND LIFTER.

Application filed October 11, 1923.

To all whom it mag concern:

Be it known that I. JAMES L. ALLEN, a citizen of the l nited States. residing at .llemphis. in the county of Shelby and State of Tennessee. have inventedcertain new and useful Improvements in Combination Valve Grinders and Lifters. of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a combination valve grinder and lifter especially adapted to be used for grinding the valves of an internal combustion engine. the object being to provide a device which can be quickly attached to the block of the internal combustion engine so that all of the springs of the valves can be removed and the valves ground after'the device has been once placed in position. I

Another object of the invention is to provide novel means for mounting the valve turning tool so that it can be swung over the block in position to grind any of the valves of the engine.

A still further object of the invention is to provide novel means for mounting the lifting tool so that it can be moved along the guide bar in position to lift the valve to remove the spring.

Other and further objects of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings,

Figure 1 is a top plan view of a block of a four-cylinder engine showing the application of my improved construction of valve grinder and lifter thereto;

Figure 2 is a detail side elevation showing the manner of using the lifter;

Figure 3 is a detail side elevation showing the grinder in position to operate; and

Figure 4 is a detail view of the guide for the lifting tool.

In the drawing 1 indicates the block of an internal combustion engine provided with the usual valves 2 held on their seats by springs 3. the above description being given so that the operation of my combined grinder and lifter can be clearly understood.

In the embodiment of my invention as herein shown, I provide a frame composed of a main bar 4, end bars 5 and 6 arranged at right angles to the bar 4 and secured thereto by bolts 7. said bars being provided with apertures through which bolts 8 are Serial No. 667,972.

adapted to pass for securing the same on the block of an internal combustion engine.

The end bars 5and 6 are'provided with apertures through which extend the-upward- 1y projecting ends 9 of a bar 10. which is substantially U shaped and lies in a plane below the bar 4 for the purpose hereinafter fully described.

The ends of the bar 10 are threaded and carry thumb nuts 11 for securing the bar in itsadjusted positionwherebythe position of the bar 10 in respect to the bar 4 can be adjusted so as to place thebar in a proper position to allow the springs to be lifted to remove the same as will be later described.

Slidably mounted on the bar 10 is a sleeve 12 to which is pivotally connected a sleeve 13 in which is slidably mounted a. valve lifting tool 14 which is provided with a bifurcated end for embracing the valve stemso as to compress the spring inorder to allow the spring retaining member to be with-- drawn from the stem so that the springs of the valve can be removed so that the valve can be ground with my improved construction of grinding means as will be later described. By mounting the sleeve'12 on the bar 10 so that it can slide, the lifting tool 14.- can be moved in position to operate on any one of the valves of the engine and in Figure 2 I have shown the tool in engagement with the spring so that the retaining member can be removed in order to detach the spring from the valves.

Pivotally mounted on thebolt 15 secured on the bar 4 is a lever 16 which carries a pivoted arm 17 at its upper end, said arm being pivotally mounted on bolt 18 so that by tightening the nut of the bolt, the arm 17 can be locked in its adjusted position in respect to the lever 16. The arm 17 is pro vided with a vertical bore 19 forming a bearing for a valve tool 20, which carries a gear 21 adapted to mesh with the gear 22 fixed on a crank 23 whereby the tool ,20 can be rotated by turning the crank so as to either continuously rotate the valve on its seat or to oscillate the same as by swinging the crank back and forth, the valve tool will be' oscillated so as to oscillate the valve in order to grind the same.

The tool 20 is adiustably mounted within the arm 17 by forming the upper end threaded as shown at 21' and securing the same by a nut 21.

By this construction the lever can be swung around into various positions and locked by its pivoted bolt so as to move the arm carried thereby in such a position that the tool will engage the head of the valve so as to oscillate the valve for grinding the same.

From the foregoing description it Will be seen that I have provided a combination valve grinder and lifter in which a frame is employed capable of being bolted to the block of the engine and having agrinding toolanda lifting tool adjustably mounted on the frame so that the tools can be moved into position to engage the respective valves.

What I claim iS.'-

1. A valve grinder and lifter comprising a frame having bars in different horizontal planes, one of said bars having a lifting tool support slidably mounted thereon and the other bar having an arm carrying a valve grinding tool. I

2. A device of the kind described coii'iprising a frame adapted to be bolted to the block of an engine, of a lever pivotally mounted in said frame, an arm adjust-ably mounted on said lever, a tool adjustably mounted in said arm, a gear carried by said tool and a crank mounted on said arm having a gear meshing with the first mentioned gear for oscillating said tool.

3. A valve grinder comprising a frame adapted to be bolted to the block of an engine and a lever pivotally mounted on said frame, an arm pivotally mounted on the end of said lever, means for locking said arm in adjusted position in respect to said lever, a valve grinding tool adjustably mounted in said arm, a crank mounted in said arm carrying a gear and a gear carried by'said tool meshing with said gear.

4. A combined valve grinder a id lifter comprising a frame adapted to be bolted to the block of an engine having bars extending parallel With the side of the engine block and arranged in different horizontal planes, the lower bar being provided with a slidably mounted sleeve carrying a tool holding sleeve and the upper bar being provided with a lever having an adjustable arm carrying a grinding tool.

A valve grinder comprising a frame adapted to be bolted to the block of. an engine having a pivoted lever capable of swinging over the top of the block, said lever having a pivoted arm at its free end, means for locking said arm in adjusted position, a valve grinding tool mounted in said arm and means carried by said arm for oscillating said tool. I

In testimony whereof I hereunto atiix my signature.
